Like Bajrang Dal, many Muslims have sacrificed lives for cow protection: RSS chief

London/Milan, Jun 2: World Health Organization experts and a range of other scientists said on Monday there was no evidence to support an assertion by a high profile Italian doctor that the coronavirus causing the COVID-19 pandemic has been losing potency.

Professor Alberto Zangrillo, head of intensive care at Italy's San Raffaele Hospital in Lombardy, which bore the brunt of Italy's COVID-19 epidemic, on Sunday told state television that the new coronavirus "clinically no longer exists".

But WHO epidemiologist Maria Van Kerkhove, as well as several other experts on viruses and infectious diseases, said Zangrillo's comments were not supported by scientific evidence.

There is no data to show the new coronavirus is changing significantly, either in its form of transmission or in the severity of the disease it causes, they said.

"In terms of transmissibility, that has not changed, in terms of severity, that has not changed," Van Kerkhove told reporters.

It is not unusual for viruses to mutate and adapt as they spread, and the debate on Monday highlights how scientists are monitoring and tracking the new virus. The COVID-19 pandemic has so far killed more than 370,000 people and infected more than 6 million.

Martin Hibberd, a professor of emerging infectious disease at the London School of Hygiene & Tropical Medicine, said major studies looking at genetic changes in the SARS-CoV-2 virus that causes COVID-19 did not support the idea that it was becoming less potent, or weakening in any way.

"With data from more than 35,000 whole virus genomes, there is currently no evidence that there is any significant difference relating to severity," he said in an emailed comment.

Zangrillo, well known in Italy as the personal doctor of former Prime Minister Silvio Berlusconi, said his comments were backed up by a study conducted by a fellow scientist, Massimo Clementi, which Zangrillo said would be published next week.

Zangrillo told Reuters: "We have never said that the virus has changed, we said that the interaction between the virus and the host has definitely changed."

He said this could be due either to different characteristics of the virus, which he said they had not yet identified, or different characteristics in those infected.

The study by Clementi, who is director of the microbiology and virology laboratory of San Raffaele, compared virus samples from COVID-19 patients at the Milan-based hospital in March with samples from patients with the disease in May.

"The result was unambiguous: an extremely significant difference between the viral load of patients admitted in March compared to" those admitted last month, Zangrillo said.

Oscar MacLean, an expert at the University of Glasgow's Centre for Virus Research, said suggestions that the virus was weakening were "not supported by anything in the scientific literature and also seem fairly implausible on genetic grounds."

Marriages will have to shed decadence as the state government, in an advisory, has restricted the number of guests to 50 and barred consumption of liquor at such events. 

The advisory was issued in anticipation that the COVID-19 lockdown will be eased in a phased manner. 

The advisory, issued by the Department of Health & Family Welfare, states that events can be held in a “suitable public place with good natural ventilation (no air condition).”

All guests must have the Arogya Setu app on their phones and the contact details all marriage attendees should be maintained. 

No person from a containment zone will be allowed to attend the event, and persons aged above 65 years, pregnant women and children below 10 years are not permitted. 

Sanitizers are to be provided at the entry and at “appropriate” places. Thermal screening is a must at the entry point of the venue. The scanner should be held 3-15 cm away from a person’s forehead. “Anyone found having a fever (37.5 degree centigrade or 99.5 farenheit), cold, cough, difficulty in breathing shall not be permitted to attend the event and immediately referred to seek medical advice,” the advisory said. 

Besides prohibition on consumption of alcohol, the advisory said paan, gutka and tobacco will not be allowed. 

Face masks are compulsory and all persons should maintain a physical distance of more than one metre. The venue shall be clean and hygienic, with a prohibition on spitting in public places.

A nodal person should be identified to oversee the arrangements, the advisory said.
